Answer:
Q'(-6, 9), R'(-9, 3), T'(6, -3), W'(6, 12)
Step-by-step explanation:
Each of the individual coordinate values is multiplied by 3.
(x, y) ⇒ (3x, 3y)
__
Q(-2, 3) ⇒ Q'(-6, 9)
R(-3, 1) ⇒ R'(-9, 3)
T(2, -1) ⇒ T'(6, -3)
W(2, 4) ⇒ W'(6, 12)
Answer:
x=8
Step-by-step explanation:
If it's a vertical line that means it's "sticking straight up" in a sense, so your line would go through all values of 8.
X would be -3/8 or in decimal form 0.375
<em>x₁ = 5</em>
<em>x₂ = - 2</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>x² - 3x - 10 = 0</em>
<em>x² + 2x - 5x - 10 = 0</em>
<em>x(x + 2) - 5(x + 2) = 0</em>
<em>(x - 5)(x + 2) = 0</em>
<em>x - 5 = 0 => x₁ = 5</em>
<em>x + 2 = 0 => x₂ = - 2</em>
<em>Good luck !</em>
